The present disclosure relates to a transmission method and device in a wireless communication system, and more particularly to a method and device for supporting data transmitting on an unlicensed spectrum.

In the traditional 3GPP (3rd Generation Partner Project) LTE (Long-term Evolution) system, data transmission can only occur on the licensed spectrum, but with the sharp increase of data transmission traffic, especially in some urban areas, licensed spectrum may be difficult to meet the demand for data transmission traffic. The communication on the unlicensed spectrum in Release 13 and Release 14 is introduced by the cellular system and used for the transmission of downlink and uplink data. In order to ensure compatibility with access technologies on other unlicensed spectrums, LBT (Listen Before Talk) technology is adopted by LAA (Licensed Assisted Access) of LTE to avoid interference caused by multiple transmitters occupying the same frequency resource at the same time.

The uplink transmission in the traditional LTE system is often based on the grant of the base station. In order to avoid the resource utilization degradation and delay caused by the frequent use of LBT, the AUL (Autonomous Uplink) transmission is introduced in the unlicensed spectrum in Release 15. In the AUL, the UE (User Equipment) can perform uplink transmission independently in the air interface resources pre-configured by the base station. At present, 5G NR (New Radio Access Technology) access technology for unlicensed spectrum is under discussion. Large-scale MIMO will be used on a large scale in 5G NR, and unlicensed spectrum grant-free uplink transmission needs to be reconsidered.

Through the research, the inventors found that how to avoid frequent LBT in the uplink transmission on the unlicensed spectrum of the NR system, effectively realize the sharing of unlicensed spectrum resources by multiple UEs, and improve the transmission efficiency of unlicensed spectrum is a key problem to be solved.

In response to the above problems, the present disclosure discloses a solution. It should be noted that, in the case of no conflict, the features in the embodiments and the embodiments of the present disclosure may be combined with each other arbitrarily.

The present disclosure discloses a method for wireless communication in a user equipment, which includes:

Receiving a first information, the first information is used to indicate a first parameter, the first parameter is associated with one of the L spatial parameter sets, and the L spatial parameter sets are respectively in one-to-one correspondence with L time domain resources, where L is a positive integer greater than one;

Transmitting a first wireless signal in a first time domain resource of a first sub-band, the first time domain resource being one of the L time domain resources;

Wherein the first sub-band includes a frequency domain resource occupied by the first wireless signal; wherein the L time domain resources belong to a first time window, and the first information is used to determine the first time domain resource from the L time domain resources; the first parameter is used to determine transmitting antenna port group of the first wireless signal; the antenna port group is composed of a positive integer number of antenna port(s).

In one embodiment, the problem to be solved by the present disclosure is that multiple UEs can share the same unlicensed spectrum resource in order to improve resource utilization. In order to reduce interference between multiple UEs, the base station may allocate different time domain resources or initial transmitting time to different UEs. Under this mechanism, in order to improve the utilization of spectrum resources, which UEs can occupy the same time domain resources or the initial transmitting time is a key problem to be solved.

In one embodiment, the essence of the foregoing method is that the first parameter represents UE beam, the L spatial parameter sets are L beam sets, the different beam sets correspond to different time domain resources or the initial transmitting time, and the UE beam is in which range of the beam set, the uplink wireless signal is transmitted at the time domain resource corresponding to the beam set or the initial transmitting time. Multiple beams in a beam set may have low correlation or long-distance deviation, so that when multiple UEs respectively use multiple beams in one beam set to simultaneously transmit uplink wireless signal, inter-user interference is small, so that the base station can solve the wireless signal of the multiple UEs. If the correlation between two UE beams is large or the direction is adjacent, through the two beams may be respectively corresponding to different time domain resources or initial transmitting times to reduce inter-user interference, thereby ensuring that the base station successfully solves the uplink wireless signal. The advantage of the above method is that the sharing of unlicensed spectrum resources by multiple UEs is effectively implemented, the mutual interference between users is reduced, and the transmission efficiency of the unlicensed spectrum is improved.

The advantage of using the above method is that different UEs can occupy different time domain resources or initial transmitting time in different time windows of the M time windows, and avoid the situation that a specific UE always preempts the channel before other UEs.

In one embodiment, the foregoing method has the advantage that the unfairness of other UEs caused by a certain UE occupying the channel preemptively in all time windows in the M time windows is avoided.

In one embodiment, the foregoing method has the advantages that different UEs can be allocated different time domain resources or initial transmitting time in the same time window of the M time windows to avoid interference between UEs, and the time domain resource occupied by one UE or the initial transmitting time changes with time, thereby avoiding the unfairness of channel occupancy between UEs caused by the specific UE always preempting the channel before other UEs.

Layer 1 (L1 layer) is the lowest layer and implements various physical layer (PHY) signal processing functions, and layers above layer 1 belong to higher layers. The L1 layer will be referred to herein as PHY. Layer 2 (L2 layer)is above PHYand is responsible for the link between the UE and the gNB through PHY. In the user plane, L2 layercomprises a media access control (MAC) sub-layer, a radio link control (RLC) sub-layerand a packet data convergence protocol (PDCP) sub-layer, and these sub-layers terminate at the gNB on the network side. Although not illustrated, the UE may have several upper layers above the L2 layer, further comprising a network layer (e.g. an IP layer) terminated at the P-GW on the network side and terminated at the other end of the connection (e.g. Application layer at the remote UE, server, etc.). The PDCP sub-layerprovides multiplexing between different wireless bearers and logical channels. The PDCP sublayeralso provides header compression for upper layer data packets to reduce wireless transmission overhead, and provides the security by encrypting data packets, and provides handoff support for UEs between gNBs. The RLC sublayerprovides segmentation and reassembly of upper layer data packets, retransmission of lost packets and the reordering of data packets to compensate for the disordered reception resulted by the hybrid automatic repeat request(HARQ). The MAC sublayerprovides multiplexing between the logical and transport channels. The MAC sublayeris also responsible for allocating various wireless resources (e.g. resource blocks) in one cell between UEs. The MAC sublayeris also responsible for HARQ operations. In the control plane, the wireless protocol architecture for the UE and gNB is substantially the same for the physical layerand the L2 layer, but there is no header compression function for the control plane. The control plane also comprises an RRC (Wireless Resource Control) sublayerin Layer 3 (L3 layer). The RRC sublayeris responsible for obtaining wireless resources (i.e. wireless bearers) and configuring the lower layer using RRC signaling between the gNB and the UE.
